Nah it's not cringe to celebrate, it's cringe to make a low effort meme that either tries to guilt or trick people into upvoting. A good example is ''grr! I'm so mad lettuce gets upvotes! Upvote my meme instead!'' being that this is 1. Not that and 2. An excellent use of the surprised pikachu meme, i'd say good job.
you're kinda evading the question here. I'm more or less just asking why you gotta be toxic and NOT just be supportive for this probably new user? being nontoxic makes it to where more people who might be scrolling without an account want to sign up and join in seeing a good community with tons of support! which, clearly imgflip has not failed to have. I'm just saying that a single user putting mean comments like this could lead people to believe this is not a good site leading to this site losing a potentially really funny person.
